Report

When jack-in a REPL from vs-code with calva, I got the following error:

java.lang.NullPointerException: Cannot invoke "jdk.javadoc.internal.doclets.formats.html.HtmlConfiguration.getOptions()" because "this.configuration" is null

Note that it does not really prevent using Calva, but it may be breaking something I am not using.

Apparently, the same error was reported for clojure-emacs [1]

Thanks for the report. Let's see what can be done upstream as it seems it needs to be fixed there.
